There are some similarities between the pretribulational rapture and post-tribulational gathering of the saints. For instance, trumpets are sounded (pre: 1 Cor 15:52; post: Matt 24:31;), and a resurrection takes place (pre: 1 Thess 4:16; post: Isa 26:19; Dan 12:2; Rev 20:5). Despite these similarities, however, there a number of differences between these two events, indicating that they are indeed two separate events. Though more could be added, here are at least some of the primary differences between the pretribulational rapture and post-tribulational gathering of the saints.
